Foaming Oil

[quad97]

I just changed the break in oil out of my KTM 525 and put in Amsoil 20W-50. As soon as I changed it and started the bike up the oil got milky like it had water in it, but it is air bubles, not water or antifreeze. I have run Amsoil 20W-50 in my other bikes without problems so I do not think it is the oil. I removed both oil filters and it looked normal in both cavities. Both of the screens are in correctly I think. The narrow end of the one screen goes in first, right?.

Any suggestions would be greatly appreciated.

The break-in oil will make new oil look like that if it still has break in oil in it ( at least it does on our new kawi and yamaha models). I would just change it again and then look at it .
